RAIL-JOINT.

No. 848,156. d

To lall mil/0711, t 1li/wy nance-771,:

Be it known that I, BENJAMIN G. BU- cH-ANAN, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Wisconsin, have invented certain new and useful Improvements in Rail- Joints, of which the following isa Aspecification, reference being had therein to the accompanying drawing.

The invention relates to rail-joints, and has for its obj ect to provide a device of this character that can contract and expand and at all times present a smooth, continuous, and cornparatively noiseless tread tov the car-wheel passing over the same.

-A further obj ect of the invention is to provide a rail-.joint which will keep each end of the rail foi-ming the joint in exact registration. 'f

These and other objects 'will a ear from the hereinafter descri tion and il ustration i in the accompanying rawings, in which.

Figure l is a perspective view of a railjoint constructed in accordance with this inf vention. Fig. 2 is a detail perspective view ofthe ends apart. Fig. 3 is a cross-sectional view of the two sections of the chair.

Referring to the drawings, 1 and 2 designate the ends of the rails 'forming the iniproved joint. The rail end 1 is provided with a wedge-shaped tongue 3,which extends half-way to the bottom of the tread and is received in the recess of like configuration in the adjacent rail 2. The en'd of the tongue 3 is inclined to the vertical for the purpose of forcing dirt or small pebbles out when the 'oint contracts and expands, as, will be read- 115T understood.-

The joint is seated in a strong chair having two sections which coperate with the tongue in keeping the two rails in exact registration. The tongue 3, in'addition to being inclined or beveled at the end, is also beveled on each side, as shown at 3 in Fig. 2 of the drawings. This tongue enables the tread of .the joint to present a smooth continuous face to the wheels passing thereover, and the beveled sides, in addition to forcing sand and Specicaticn of Letters 'Patent'.

pebbles out which may be washed therein, ro'vide a safeguard against thetongue from being battered, as will likely* result from long use.

The two sections 4 and 5 of the chair are bolted together by bolts 6, which pass through the web of the rails. The two sections of the chair have each a strong integral brace 7, which is also integral witha shoulder 7, which engages the4 tread of the rail from beneath and which gives added Astrength to thel two sections aforesaid at the joint of the rai s. of a side 8 and a base portion 9, forme inte# gral with each other. Depending from the base portions 9 are depending ears 1v1, which` are integral with the c air and are pierced by bolts 10, which iirmly clamp the base portions together.

In order vto enable the 'oint to perfectly free itself from pebbles and sand automatically, recesses 8a are provided in the shoulders 7 a, which will cause the said sand or pebbles to dro down instead of clogging up the joint w en the rails are contracted.

1. A rail-joint chair composed of two sections, said sections engaging the base and sides of the rails, a 4longitudinal shoulder fornied integral with each section and engaging the tread of the rails at the joint, said shoulders having-a recess for the escapernent of matter falling into said joint.

2.. A rail-joint comprising a pair of abutting rails, one of said rails, having agroove provided with vertical walls, and saidl other rail, having a tongue engaging said groove, *the side and end walls of said tongue being convergent toward! the top, whereb` foreign ,matter will be forced out, when the rails` QX- pand. v

In testimony whereof I hereunto ainsi :n 'signature in presence of two witnesses.
